T at whom, it may concern:

Be it known that I, NoYEs F. PALMER, of Jamaica, Queens county, State of New York, have invented a new and Improved Fountain- Pen, of which the following specification is a full, clear, and exact description.

This invention relates to an improvement in fountain-pens whereby a double feed-one at bottom and one at top of the p enis obtained.

Theinvention relates to thevarious features of improvement, hereinafter more fully described. I

In the accompanying drawings, Figure 1 is a vertical longitudinal section of a fountainpen with my improvement. view of the same. Fig. 3 is a longitudinal section of the bottom feed-block. Fig. 4 is a top view of the same. Fig. 5 is a cross-section of the same at line 00 00, Fig. 3. Fig. 6 is a top view of the pen-plug. Fig. 7 is a bottom view of pen-plug, pen, and bottom feed. Fig. 8 is a top view of the pen-plug with pen in place. Fig. 9 is a cross-section at line z 2, Fig. 8.

A represents the usual hollow handle or reserv oir to contain the ink, provided at its closed end with the usual nipple, a, to receive the cappiece B when the pen is in use. The opening at the other end of this handle is threaded to receive the hollow upper feed and pen-plug, G.

This plug receives the gold or other pen, P, and is providcdin its inner cavity with a small shoulder, s, for the end of the pen to bear against. By this arrangement the pen, after having been removed, will always find its exactposition when again replaced into the plug. This plug C is provided with a long narrow or;- tcnsion-tongue, d, lying on the top and proj ecting some distance over the slit of the pen. Into the central hollow part of this plug 0 the lower feed-plug, E, is inserted. The end f of this feed-plug fits tightly into the central opening of the plug 0, and is provided with a central cavity, and a small channel, 71., on top connecting with the interior of the reservoir A. This channel h connects through an opening, 1', with the central cavity, g, anda corresponding opening, k, leads from this central cavity, 9, downward, and connects there with a channel, Z, extending from this opening is to the end of the feed-plug O. From the circular end f of this lower feed-plug, E, extends a pro- Fig. 2 is a side.

jection and tongue, e, fitting against the inside of the pen as closeas possible, while the outside of this tongue e is tapered off and is'extended nearly to the point of the pen. On the inside of this tongue e, or the side nearest the pen, a channel, a, is made, extending nearlyto the extreme point of the tongue, and connected with channel h on top of the plug. (See Fig. 4.)

The operation is as follows: The hollow handle orreservoir A is filled with ink, the upper feed-plug, O, screwed into the threaded open end, and the central plug, E, inserted into this plug 0, when the pen I? is inserted between the plugs O and E till it bears against the shoulder s,when the pen will be ready for operation, regulating automatically the flow of ink and air in all cases,whether,fine lines or broad heavy lines are to be made. When the pen is pressed upon the paper, capillary attraction and gravity draw the ink from the handle or reservoir, according to the openingof the nibs of the pen. Air flows then through the openings k and ito the channel h freely when the nibs of the pen are spread far apart for very heavy lines or writing, while when the pen -nibs are but slightly opened the air will flow only slowly. In other words, the flow of air will be directly in proportion with the opening of the nibs of the pen. 1f this would not be so, the ink would flow entirely from the hollow handle whenever the position ofthe pen was with its point downward. The ink lying in the channel a in the tongue 6 close to the point of the pen on the under side allows a ready starting, and after starting, and during heavy-line making and shading, the ink-flow is maintained by the top tongue-extension, d,'of the upper feed, the ink passing from the channel a in the lower tongue through the slit in the pen into the cavity formed between the top of the pen and the under side of the'tongue (1, said tongue being slightly bent upward by the bending of the pen during the operation'of writing.

Itis well known to those skilled in adjusting this class of pens that only a bottom feed is very troublesome and insufficient in heavyline writing, for the reason that the pressure upon the pen, and the consequent bending of the same upward, leaves the bottom feed channel inoperative without giving the feed too much vent for the ordinary fine-line writin g.

The combination of a bottom feed with a top feed entirely relieves this trouble.

I claim as my invention 1. In a fountainpen, the combination of the handle or reservoir A, pen-plug O, pen P, and central plug, '13, with a projection or tongue,d, attached to the pen-plug C and lying upon the pen over the slit, and a projection or tongue, 0, lying against the inner side of the pen and extending nearly to the point of the pen, substantially as specified.

2. In a fountain-pen, the combination of the pen-plug O with the hollow central feedplug, E, provided with a central longitudinal cavity, and channels it and Z, and with opening 11, connecting the cavity g with the channel h, and opening it, connecting the cavity 9 with the channel 1, operating in combination with .the pen and ink in the reservoir in the manner substantially as set forth.

3. The combination of pen-plug 0, having tongue d, with the feed-plug E, provided with tongue 6, cavity g, openingi, and channel h,and channel a on the face of the tongue 0, and forming a continuation of the channel h, substantially as described.

4. In a fountain-pen, the combination of a pen with a top feed consisting of a tongue attached to the pen-plug and lying upon the pen over the slit, and a bottom feed consisting of a tongue attached to the central hollow feedplug and extending nearly to the point of the pen, and provided with an ink-channel connected to the central cavity of the plug and to a channel on top of said plug, substantiallyas and for the purpose specified.

5. In a fountain-pen, the combination, with the plug G, of a hollow central feed-plug, E, provided with a forwardextending tongue, e, central cavity, 9, top channel, h, connecting with the ink-reservoir, the opening k, and channel 1, connecting with the outer end of the pen-plug O, substantially as and forthe pun,

pose set forth.

6. The combination, in a fountainpen, ofa top feed extending over the top of the slit of the pen, with abottom feed-plu g provided with an ink-duct extending underneath the slit of the pen, substantially as described.
